The result is a sort of cafe mole, complete with an enticing chocolate beginning and palpable heat at the end that sits in the back of your throat long after each sip. Agave provides balanced sweetness without sugar. The espresso (from their own brand of beans, Dark Matter, also in many Chicago restaurants) provides a huge buzz, plus hints of peanut butter and walnut.
